Exploration Game: Others Survive, but I Build Mechas

The exploration game starts, and all humans are scattered in closed areas in different environments. If you want to survive, you have to explore other areas. In other areas, there may be resources or terrifying monsters. It may be other civilizations, it may be the boss that destroys everything. And the consultant seems to be a bug in this game! He can see the synthesis list of all items. So, while other players were still panicking, he had already entered the Iron Age. While other players are still struggling, the consultant starts hunting monsters. "Is that the boss?" "No, then he is a big consultant! What is he wearing?" "Is that a mecha!? While we were still struggling for a bite of food, the consultant boss was already on the Gundam!?" This novel and its characters are purely fictitious.
